ENGINE CONTROL SYSTEM 3-32
O
2
FEEDBACK SYSTEM
After extended usage, the engine components may become deteriorated or worn out.
This might make the A / F (air / fuel mixture ratio) incorrect which could affect exhaust emissions. To correct
the A/F, an O
2
sensor is temporally installed to the exhaust manifold. This sensor is used to measure the
concentration of oxygen in the exhaust gas at engine speeds of 2500, 3500 and 4500 r/ min.
The ECM uses the input data from the O
2
sensor to correct the compensation coefficient of the fuel injection
duration map within the ECM itself.
NOTE:
See the “FUEL MIXTURE CHECK (O
2
FEEDBACK)” section on page 2-21 for the O
2
feedback operation
procedure.
